| Question | Answer |
|---|---|
| abiotic | Non-living things |
| biotic | living things |
| watershed | The land from which surface water drains into a particular river, lake, wetland, or other body of water. |
| Estuary | A habitat in which the fresh water of a river meets the salt water of the ocean. |
| habitat | Place where an organism lives. These are provided by wetlands. |
| divide | a ridge of land that separates one watershed from another |
| runoff | water that flows over the ground surface rather than soaking into the ground |
| Tributary | A stream or river that flows into a larger river |
| point source pollution | pollution that comes from a specific site |
| non-point source pollution | water pollution that does not have a specific point of origin |
| Salinity | A measure of the amount of dissolved salts in a given amount of liquid |
| temperature | A measure of how hot or cold something is. |
| Turbidity | A measure of how clear water is. |
| Dissolved Oxygen | the amount of oxygen in the water |
| pH scale | scale with values from 0 to 14, to measure how acid or basic something is. |
| Macroinvertebrates | organisms without backbones, which are visible to the eye without the aid of a microscope. |
| wetland | A land area that is covered with a shallow layer of water during some or all of the year. These act as filters for water, natural buffers from storms, and habitats for plants and animals. |
| renewable resources | natural resources that replenish themselves naturally over short periods and are typically much better for the environment |
| nonrenewable resources | natural substances that are not sustainable as they take millions of years to form; typically very bad for the environment |
| States of the Chesapeake Bay Watershed | Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia |
| 5 largest tributaries of the Chesapeake Bay Watershed | Susquehanna, Potomac, James, Rappahannock, and York rivers |
| River | a natural, flowing body of freshwater water that flows downstream toward a larger body of water |
| Bay | an inlet of brackish water partially enclosed by land, typically providing a sheltered harbor |
| Ocean | a large, continuous body of salt water covering over 70% of Earth's surface |
| Examples of Nonrenewable Resouces | Fossil Fuels (coal, petroleum oil, natural gas); Nuclear |
| Examples of Renewable Resources | Wind, Hydroelectric, Photovoltaics, Solar, Biomass, Geothermal |
